Before Hennegan Brothers took flight, John worked in various creative environments in television, radio, print and film, with a special focus on writing and physical production. The Hennegan Brothers wrote, produced, filmed and edited "First Saturday In May", one of the greatest racing documentaries ever created. It chronicles the journey of a diverse cast of six hard-working trainers as they jockey for position along the 2006 Kentucky Derby trail. In addition to providing and inside look at the amazing people who dedicate their lives to the sport of horse racing, the film features never-before-seen footage of a young Barbaro – the horse who captured the fascination of the world. After attending the University of Virginia, John now calls Brooklyn, NY home with his wife and two children. In between trips to the racetrack, they foolishly root for the Mets, Giants and Rangers.
